Birmingham City boss Alex McLeish says Mikael Forssell can be crucial in their bid to survive relegation.
"I think Mikael had such an affection for this club and he wanted to come back here.
"I've seen him in international football - and we got an international type performance against Reading from Mikael. We just hope we can keep him fit because he is very important to the squad.
"We definitely are looking to Mikael to be a big player for us."
